What are some examples of infrared radiation?
The heat that we feel from sunlight, a fire, a radiator or a warm sidewalk is infrared. The temperature-sensitive nerve endings in our skin can detect the difference between inside body temperature and outside skin temperature.
What are the health risks of infrared radiation?
Prolonged exposure to IR radiation causes a gradual but irreversible opacity of the lens. Other forms of damage to the eye from IR exposure include scotoma, which is a loss of vision due to the damage to the retina. Even low-level IR absorption can cause symptoms such as redness of the eye, swelling, or hemorrhaging.
What are some benefits of infrared waves?
Infrared therapy has many roles in the human body. These include detoxification, pain relief, reduction of muscle tension, relaxation, improved circulation, weight loss, skin purification, lowered side effects of diabetes, boosting of the immune system and lowering of blood pressure.
What are advantages and disadvantages of infrared?
➨Infrared frequencies are affected by hard objects (e.g. walls, doors) , smoke, dust, fog, sunlight etc. Hence it does not work through walls or doors. ➨Infrared waves at high power can damage eyes. ➨In monitor & control application, it can control only one device at one time.
How can you protect yourself from infrared radiation?
To protect against infrared radiation it is necessary to use a special shield or goggles. Almost all the materials for glass and plastic lenses block ultraviolet radiation less than 300 nm and infrared radiation with wave length over 3,000 nm (3).
What are the advantages and disadvantages of infrared technology?
They consume much less power and are much more compact. It covers a much “wider range” of area seamlessly. The disadvantages of infrared wireless technology are: The devices have to be in stable position during the transmission and this technology can currently only be used for “short distance communications”.”
Does infrared skin tightening work?
This suggested that IR radiation treatment at an ambient temperature is safe and does not cause harmful thermal injuries. Our results further suggest that IR radiation may result in beneficial effects on skin texture and wrinkles by increasing collagen and elastin in the dermis through stimulation of fibroblasts.
What is use of infrared?
Infrared (IR) light is used by electrical heaters, cookers for cooking food, short-range communications like remote controls, optical fibres, security systems and thermal imaging cameras which detect people in the dark. The heating effect of IR can cause burns to the skin.
How is infrared radiation harmful to the human body?
Infrared radiation can only penetrate approximately 4 cm into the human body, so the primary risks of infrared radiation exposure are to the skin and the eyes. Although it is not a primary contributor to skin cancer, purposefully increasing your infrared radiation may increase your risk of other health issues .
Are there any health benefits to infrared therapy?
Also, infrared light is safe, natural, non-invasive, and painless. Thus it may be able to provide a broad range of health benefits. Infrared treatment for rehabilitation orthopedic medical care.
Is it safe to use an infrared heater?
Those who have experienced infrared heaters know first-hand the comfortable heat they create. Nonetheless, many still have doubts and fear that infrared radiation is hazardous to their health. After all, most associate the word radiation with negative things such as nuclear radiation or X-radiation.
What kind of radiation does an infrared heater use?
Infrared heatings panels work with far infrared rays (infrared-C radiation). While long and intense exposure to infrared radiation can cause harm to the eye this is only the case for extremely hot occupational applications such as in the metal welding or glass blowing industry.
